2 climbers killed on Mount Everest

Oh Hee-joon, 37, and Lee Hyun-jo, 34, from South Korea were climbing Mount Everest when they fell after reaching 27,200 feet.

They were from a Korean team of 7 that were attempting to climb the southwest face of the mountain.

Climbers attempt to climb the world's highest mountain from March to the end of May on the Nepalese side of the mountain. They go during this time because after this time it is monsoon season and that brings storms that make the climbing to dangerous.

There were 23 climbing parties from all over attempting this but heavy snow and strong winds forced them to stay at camps. 31 climbers successfully reached the top by Thursday. Included in those that reached the top were 6 Americans and 5 from Britain.

Since the first successful climb in 1953 by New Zealander Sir Edmund Hillary and Tenzing Norgay Sherpa, over 2000 climbers have been able to climb the mountain but there is about 200 that have died while trying to attempt this feat.
